摘要： Systems and methods for assisting one or more users in the production of a media work from a plurality of recordings are disclosed. In an exemplary embodiment, digital versions of the recordings are stored on a file-storage server accessible over a communications network. A media-library server provides an organized way for users to access and view the digital versions, and to associate various data files with the digital versions, such as transcription files, logging files, and storyboard documents. The exemplary media library generates web pages that enable users to search and access the digital versions from an internet browser running on a conventional personal computer. The browser also enables users to view the digital versions with a browser-compatible media viewer.

摘要： Techniques are described for encoding an audio video stream that is transmitted over a network, for example a wireless or IP network, such that an entire frame of audio and an entire frame of video are transmitted simultaneously within a period required to render the audio video stream frames by an application in a receiver. Aspects of the techniques include receiving audio and video RTP streams and assigning an entire frame of RTP video data to communication channel packets that occupy the same period, or less, as the video frame rate. Also an entire frame of RTP audio data is assigned to communication channel packets that occupy the same period, or less, as the audio frame rate. The video and audio communication channel packets are transmitted simultaneously. Receiving and assigning RTP streams can be performed in a remote station, or a base station.

摘要： Methods and apparatus are described for improving the transmission of multimedia data over wireless communication channels. These techniques include determining a physical layer packet size of the wireless communication system and determining a maximum size of a compressed header. Then, partitioning an information unit, wherein the size of the partitions are selected such that after a partition is encoded the aggregate size of the encoded partition and the compressed header are the size of the physical layer packet, or less. The techniques can be used for various types of information units, such as multimedia data, variable bit rate data streams, video streams, video teleconference stream, or voice over IP. The techniques can also be used with various over the air interfaces, such as, Global System for Mobile Communication (GSM), General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), or standards based on CDMA such as TIA/EIA-95-B (IS-95), TIA/EIA-98-C (IS-98), IS2000, HRDP, cdma2000, Wideband CDMA (WCDMA), and others.

摘要： A method is provided to dynamically encode data at runtime with a tagged data element in a program associated with an obfuscation algorithm randomly selected during runtime. Instructions for invoking the obfuscation algorithm are generated when a compiler encounters the tagged variable in the source code. At runtime, unencoded data is encoded by the obfuscation algorithm when the unencoded data is copied to the tagged data element; encoded data is re-encoded by the obfuscation algorithm when the encoded data is copied from a differently tagged data element to the tagged data element, wherein the differently tagged data element is associated with a different obfuscation algorithm; and encoded data is decoded by the obfuscation algorithm when the encoded data is copied from the tagged data element to an untagged data element.

摘要： This invention relates a field programmable gate array ("FPGA") offload module and process for frame-level switching of media streams in real-time. Previously, IP/Ethernet switches were not designed to switch IP streams on designated packet boundaries, or to align streams in preparation for IP switching. Embodiments of the present invention use a FPGA offload module and a process for seamless frame-level switching of media streams in real-time. Specifically, the FPGA offload module and process for seamless frame-level switching of media streams in real-time includes hardware offload at an IP/Ethernet switch port, supporting switch software to enable seamless switching, and supporting endpoint hardware and software to utilize seamless switching, thereby allowing video streams to be switched exactly between frames, and for switching losses to be recovered.

摘要： Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.

摘要： An approach for cached content identification for adaptive data streaming. A first request is received, requesting a current segment from a sequence of segments from a data file of a streaming data session. A NewVideoFlag is determined as indicating that the sequence of segments associated with the first request is not currently being cached. The first request is forwarded to a content server, and a first response message is received. A SegmentID of the received content segment is determined as not matching that of cached content segments. The NewVideoFlag is set to indicate that the segments from the streaming data session file are currently being cached. A global cVideoFilelD is generated identifying the streaming session data file being cached. The content segment is cached, and cache bookkeeping is updated to associate the segment with the SegmentID and the cVideoFilelD. The first response message is provided to the client device.
